   - Core compatible interpreted experiment enrollment now matches core reference interpreted experiment enrollment from python version of planout.

+- Separated the concerns of planout core random operations, and the planout API. The planout.js API (experiment, assignment, namespace, etc) are now composed with the random operations they are passed. This change has no effect on the usage of planout.js and only affects the development experience for contributors.
 - Added ```planoutAPIFactory.js``` to keep planout bundles consistent, and to make it easier to compose new planout bundles with the random operations of choice.
 - Made experiment & namespace names required to fix https://github.com/HubSpot/PlanOut.js/issues/57
+- Fixes ```WeightedChoice``` with false-y choices.
+- Fixes tests on windows + running the travis tests on windows as well if this is possible.
 
 ##Changes in 3.0##
